Extrusion International 1-2023

26 Extrusion International 1/2023 CHINAPLAS 2023 Solutions for an Eco-friendly and Sustainable BO Film Production Brückner’s show highlights pave the way for future processes and applications. I n addition to the developments for the rapidly developing circular economy, Brückner Maschinenbau is also sticking to its ambitious goals for further increasing efficiency in film production. This means de - creasing use of raw materials, ever lower energy consumption and "zero waste" in film production. At Chinaplas 2023 in Shenzhen, latest solutions for the film stretching of the future will be presented in Hall 10, Booth 10Q21. Higher efficiency – lower energy consumption The more efficient and higher output a film stretching line is, the lower the specific energy con- sumption. These parameters can mainly be influenced by the line speed and the line width. At Chi - naplas Brückner Maschinenbau will present corresponding new line concepts for packaging film production: • Production of the most popu- lar packaging film BOPP with a line concept with an annual output above the current benchmark of 60,000 to 70,000 tons per year. This also means a two-digit lower energy consumption, based on 1 kg of film. • BO films made of polyamide (BOPA): New line types with up to 80% more output – based on an increase in production speed from 220m/min to 350m/min and line widening from 6.6m to 7.4m. More sustainability in film production • A new type of direct recycling saves energy, conserves raw mate- rial and comes very close to the goal of "zero waste" in production. • Intelligent stretching oven management ensures an energy saving of around 1.6 million kWh per year. • Aerodynamic zone separa- tion increases the proportion of A-grade film on the winder, reduc- es production waste and lowers specific energy consumption. Mono-material films – solutions for a Circular Economy: Mono-material solutions are ideal for the use in new applica- tions since they guarantee good sortability in waste separation and high-grade recycling material qual- ity. Brückner Maschinenbau has developed mono-material packag- ing solutions to close the life cycle of plastic packaging. Besides the Brückner Battery Separator Film Production Line
